Prom Watchdog Reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

On my sun4c OPUSstation (Sparc 1 clone) I regularly get tripped back to the Prom during boot:

...
ok boot vmlinuz -p
Booting from: sd(0,0,0)vmlinuz -p
root on sd0a fstype 4.2
Size: 2675008+0+142756 bytes
Booting Linux...
Watchdog reset
Window Underflow
ok

The boot prom is Revision 1.0. Is there a way of doing a full Prom reset as part of the boot sequence to try and remove this issue.

If I redo the boot or do a powerup reset boot, there is no issue at this point.

Regards
	Mark Fortescue.
